怎样实现织梦DedeCms 5.7代码块高亮

2013-04-19 17:16:07长沙做网站严微

长沙做网站的严微工作室在网站上经常发布关于织梦以及ecshop网站教程的文章,经常需要粘贴代码来说明文章。织梦自身没有插入代码高亮的功能,在网上也找了一大把,结合网上的讲解,以及自己测试后实现了该功能。在网上搜了很长时间资料,大都写的是CKEditor和SyntaxHighlighter整合的文章,但是dedecms将ckeditor做 了集成,和一般的只针对于ckeditor对config.js修改不同。所以只能自己琢磨修改了,现将方法写出供站长朋友们参考【注:下面代码是转载网上的】:【下载完整的请点我

一、首先去SyntaxHighlighter官方网站下载,网址:http://alexgorbatchev.com/SyntaxHighlighter/download/,建议下载2.1版本,3.0版本的貌似不支持自动换行,这里使用的是2.1.382版本。将下载的文件解压在syntaxHighlight文件夹里,去除里面无用的文件,只留下scripts和styles文件夹。
 
二、新建dialogs文件夹,在里面新建一个名为syntaxhighlight.js的文件,因代码量过大,不宜贴出,请直接下载syntaxhighlight.js
 
如果想修改代码区域的样式请在以下代码处修改<table>标签里的样式。

onOk : function() {  

                             var i = this.getParentEditor();  
                             var h = i.getSelection();  
                             var g = h.getStartElement();  
                             var l = g && g.getAscendant("pre", true);  
                             var j = f();  
                             this.commitContent(j);  
                             var k = e(j);  
                             var m = CKEDITOR.dom.element  
                                     .createFromHtml(‘<table style="border:1px solid #EAED9C;width:660px;"><tr><td><pre class="’ + k + ‘">’ 
                                             + c(j.code) +"</pre></td></tr><table>");  
                             if (l) {  
                                 m.insertBefore(l);  
                                 l.remove()  
                             } else {  
                                 i.insertElement(m)  
                             }  
                         },

三、然后新建images文件夹,存放一个syntaxhighlight.gif图片文件,该图片文件在编辑器工具栏上显示,可以使用16*16像素的图片
 
四、新建lang文件夹,是语言包,里面有两个文件,一个是中文cn.js一个是英文en.js,代码内容如下:
 
 en.js代码如下:

CKEDITOR.plugins.setLang('syntaxhighlight', 'en',  
 {  
     syntaxhighlight:  
     {  
         title: 'Add or update a code snippet',  
         sourceTab: 'Source code',  
         langLbl: 'Select language',  
         advancedTab: 'Advanced',  
         hideGutter: 'Hide gutter',  
         hideGutterLbl: 'Hide gutter & line numbers.',  
         hideControls: 'Hide controls',  
         hideControlsLbl: 'Hide code controls at the top of the code block.',  
         collapse: 'Collapse',  
         collapseLbl: 'Collapse the code block by default. (controls need to be turned on)',  
         showColumns: 'Show columns',  
         showColumnsLbl: 'Show row columns in the first line.',  
         lineWrap: 'Disable line wrapping',  
         lineWrapLbl: 'Switch off line wrapping.',  
         lineCount: 'Default line count',  
         highlight: 'Highlight lines',  
         highlightLbl: 'Enter a comma seperated lines of lines you want to highlight, eg <em>3,10,15</em>.' 
     }  
 });

 cn.js代码如下:

CKEDITOR.plugins.setLang('syntaxhighlight', 'cn',  
 {  
     syntaxhighlight:  
     {  
         title: '添加或更新代码',  
         sourceTab: '代码',  
         langLbl: '选择语言',  
         advancedTab: '高级',  
         hideGutter: '隐藏分割线',  
         hideGutterLbl: '隐藏分割线和行号',  
         hideControls: '隐藏工具栏',  
         hideControlsLbl: '隐藏浮动工具栏',  
         collapse: '代码折叠',  
         collapseLbl: '默认折叠代码块 (需要启用工具栏)',  
         lineWrap: '自动换行',  
         lineWrapLbl: '关闭自动换行',  
         autoLinks: '自动链接',  
         autoLinksLbl: '不自动转换超链接',  
         lineCount: '起始行号',  
         highlight: '高亮行号',  
         highlightLbl: '输入以逗号分隔的行号, 如 <em>3,10,15</em>.' 
     }  
 });

五、新建plugin.js文件,该文件是ckeditor插件必须得文件,里面是对该插件的一些配置,代码如下:

CKEDITOR.plugins.add("syntaxhighlight", {  
     requires : [ "dialog" ],  
     lang : [ "cn" ],  
     init : function(a) {  
         var b = "syntaxhighlight";  
         var c = a.addCommand(b, new CKEDITOR.dialogCommand(b));  
         c.modes = {  
             wysiwyg : 1,  
             source : 1  
         };  
         c.canUndo = false;  
         a.ui.addButton("Code", {  
             label : a.lang.syntaxhighlight.title,  
             command : b,  
             icon : this.path + "images/syntaxhighlight.gif" 
         });  
         CKEDITOR.dialog.add(b, this.path + "dialogs/syntaxhighlight.js")  
     }  
 });

六、由于dedecms 5.7自己集成了一个dedepage插件,用来添加ckeditor自定义插件,在include\ckeditor\plugins\dedepage文件夹下,打开plugin.js文件在最后面添加:
 
requires : ['syntaxhighlight'],其中syntaxhighlight为代码高亮插件的文件夹名,添加完之后的代码如下:

// Register a plugin named "dedepage".
(function()
{
    CKEDITOR.plugins.add( 'dedepage',
    {
        init : function( editor )
        {
            // Register the command.
            editor.addCommand( 'dedepage',{
                exec : function( editor )
                {
                    // Create the element that represents a print break.
                    // alert('dedepageCmd!');
                    editor.insertHtml("#_p#副标题#e_#");
                }
            });
            // alert('dedepage!');
            // Register the toolbar button.
            editor.ui.addButton( 'MyPage',
            {
                label : '插入分页符',
                command : 'dedepage',
                icon: 'images/dedepage.gif'
            });
            // alert(editor.name);
        },
        requires : [ 'fakeobjects' ],
		requires : ['syntaxhighlight']
    });
})();

注:将上段代码中的“分页副标题 ”改为以下代码:

#_p#副标题#e_#

七、修改/include/ckeditor/ckeditor.inc.php文件,在$toolbar['Basic']数组的最后一行添加元素Code,修改后代码如下:

$toolbar['Basic'] = array(
            array( 'Source','-','Templates'),
            array( 'Cut','Copy','Paste','PasteText','PasteFromWord','-','Print'),
            array( 'Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'),
            array( 'ShowBlocks'),array('Image','Flash'),array('Maximize'),'/',
            array( 'Bold','Italic','Underline','Strike','-'),
            array( 'NumberedList','BulletedList','-','Outdent','Indent','Blockquote'),
            array( 'JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'),
            array( 'Table','HorizontalRule','Smiley','SpecialChar'),
            array( 'Link','Unlink','Anchor'),'/',
            array( 'Styles','Format','Font','FontSize'),
            array( 'TextColor', 'BGColor', 'MyPage','Code')
        );

至此,编辑器的修改已经完成,修改后的syntaxhighlight文件夹文件目录结构图如下图:

将syntaxhighlight文件夹上传到/include/ckeditor/plugins/文件夹下,打开后台,添加文章试一下,看看编辑器的上最后一行是否出现了如图所示的按钮:

点击按钮弹出如下图所示的对话框输入代码,并且可以切换到高级选项对代码高亮显示做一些配置:

八、 但是光这些还不够,还要在文章模板文件/templets/default/article_article.htm文件里引入高亮显示的笔刷JS文件和 CSS文件,由于是需要引入很多JS,所以建议将引入的代码放在</body>标签之前,等待前面的网页加载完后加载,进行显示。
 
 引入代码如下:

<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shCore.js"> </script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushJava.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushJScript.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPhp.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushScala.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushSql.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushVb.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushXml.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushBash.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushCpp.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushCSharp.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/cripts/shBrushCss.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushDelphi.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushDiff.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushGroovy.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPlain.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushPython.js"></script>  
<script type="text/javascript" src="/include/ckeditor/plugins/syntaxhighlight/scripts/shBrushRuby.js"></script>  
<link type="text/css" rel="stylesheet" href="/include/ckeditor/plugins/syntaxhighlight/styles/shCore.css"/>  
<link type="text/css" rel="stylesheet" href="/include/ckeditor/plugins/syntaxhighlight/styles/shThemeDefault.css"/>  
<script type="text/javascript">  
 SyntaxHighlighter.config.clipboardSwf = '/include/ckeditor/plugins/syntaxhighlight/scripts/clipboard.swf';  
 SyntaxHighlighter.all();  
</script>

最后发表并生成的文章页面效果图如下:

  当然,该整合也有点缺点,就是在html页面页面中可能会引入大量的JS文件,加载起来可能会比较慢,另外可拓展性不强,我也会不定期优化该插件,也希望各位网友能提出意见。
